Online social spaces (e.g., social media, multiplayer games, esports, social VR, the metaverse) provide much needed connection and belonging—particularly in a context of continued lack of global mobility due to the ongoing Covid-19 pandemic and climate crisis. However, the norms of online social spaces can create environments in which toxic behaviour is normalized, tolerated or even celebrated, and occurs without consequence, leaving its members vulnerable to hate, harassment, and abuse. With this workshop, we hope to build a community of experts interested in combating online toxicity.

We invite researchers and practitioners to submit short position statements (2 pages maximum in the CHI extended abstracts format) via the workshop website that describe their knowledge and their domain of expertise, on topics such as:

• Creating frameworks, taxonomies, and definitions of online toxicity
• Understanding motivations for toxic behaviour
• Characterizing the emergence and normalization of toxicity
• Detecting toxicity through communication and behaviours
• Developing and evaluating interventions to combat toxicity
• Implementing support for the targets of toxicity
• Fostering inclusive cultures to support safer online communities
• Identifying needs of platform providers

We will accept submissions within scope of the workshop in which participants have demonstrated expertise or interest. The workshop will be in person at CHI 23 with support for remote attendees. Participants will be asked to submit an introduction video (1–2 minutes) prior to the conference, and one participant from each submission must register for the workshop and at least one day of the CHI conference. All submissions will be published on the workshop website.
